3rd Rock from the Sun

When Dick accompanies Mary on an archeological dig, he is disappointed when the only thing he finds is a small pointed rock. Mary realizes, however, that it is an ancient spearhead and becomes upset, revealing that she has never found anything before. So, in order to make Mary happy, Dick steals a ceremonial wedding moon that was found the previous day and lays it for Mary to find. Meanwhile, the Rutherford Garlic Festival is on and Sally, Harry and Tommy decide to turn their attic apartment into a hotel, but things soon become hostile between them as they attempt to make their 'hotel' good enough to get a four star rating in the Crown Travel Guide.
